Abstract

Wood deterioration were generally occured by the activities of biological agents. Fungal can attack wood and lignoselulosic substances and cause staining and decaying. Its damage levels were vary depending on the attacking fungal species. Eventhough it poses some disadvantages, actually fungy have potential benefits for human life such as nutrient, energy resources, medicine, etc. Fungy from Tabo-tabo educational forest were collected, isolated,and identified in this study. Identification was conducted throughout their macroscopic and microscopic characteristics. The result showed that the amount of fungal species were nineteen species, i.e: Aspergillus sp.,Poria subacida, Fomes sp., Lenzites sp., Hericium sp., Dacrymyces deliquescens, Ganoderma lucidum, Clitocybe sp., Trametes confragasa, Shizophyllum commune, Periconia sp., dan Helicosporium sp.,Clitocybe sp., Schizophyllum commune, dan Hygrophorus hypotejus,Ganoderma lucidum dan Coprinus atramentarius, Amanitopsis fulva dan Dacrymyces deliquescens, Collybia sp., Amanitopsis fulva, Hygrophorus hypotejus,Coprinus atramentarius, Monilia sitophilia, Gilmaniella sp. dan Conoplea sp.

Abstract

The fiber of sugar-palm tree Arenga pinnata Merr., locally known as ijuk, is traditionally used as covering to protect ground-contact wood construction materials although effectiveness of the material in protecting wood construction from biodeterioration has not been determined. In the current study, potential of the sugar-palm tree fiber as a physical barrier against termite attacks was analyzed in terms of their structure and physical characteristics. Samples of sugar-palm tree fibers from natural and marketed formations were prepared and determined for their fiber distribution, shapes, sizes, moisture content, density, and sheet grammage since these aspects were considered to be important factors influencing the penetration ability of termites. Results showed that each of the sugar-palm tree fibers has different shapes (half-round, round, rectangle) and different sizes (ranging from 0.05 to 1.00 mm in thickness). It was also found to have 3-5 ramifications with the angle of 10o – 30o. The process of branching out was supposed to initiate a natural insertion of each formed fiber to others. It is believed that fibers with particular arrangements are able to prevent the penetration or tunneling of termites. Keywords: Sugar- palm tree fiber, physical barrier, subterranean termites

Abstract

A research was conducted to evaluate the quality of white refined sugar produced from palm tree (Arenga pinnata) using direct and indirect cooking processes. Visual methods were applied to determine color, shape and texture of produced sugar. The sucrose, ash, and other sugar contents as well as dry weight of produced refined sugar were also analyzed. Results showed that the production process using direct cooking resulted in small granulated, dry, compacted and milky white refined sugar, while that using indirect cooking (four hours storage) produced clay granulated, less compacted, dust shape and browning refined sugar. The sucrose, ash, and other sugar contents found in direct cooking process were 10.27%, 0.016%. and 2.68%, respectively, while those found in indirect cooking process were 11.11%, 0.018%, and 2.78%, respectively. Keywords: Palm tree, Arenga pinnata, nira, white refined sugar

Abstract

The feasibility of a preservative treatment using carbon dioxide (CO2) as a carrier solvent under various conditions was determined based on the treatability of three different commercial tropical wood species (Agathis sp., Palaquium sp., and Heritiera sp.). Treatment was conducted at six combinations of temperature and pressure (15ºC and 40 kgf/cm2, 15ºC and 60 kgf/cm2, 15ºC and 80 kgf/cm2, 25ºC and 60 kgf/cm2, 25ºC and 80 kgf/cm2, dan 35ºC and 80 kgf/cm2) with five replicates using two specimens of each wood species for each treatment. Results showed that most of these treatment conditions, except treatment at 15ºC and 40 kgf/cm2, resulted in retention levels above the Silafluofen toxic thereshold value (< 0.25 kg/m3) without any physical damages to all treated materials. The treatability of wood with CO2 impregnation was affected by the wood properties and treatment conditions

Abstract

The bait formulation from the mixture of organic wastes for termite (Coptotermes sp) control was evaluated in laboratory and field tests. Four formulations were prepared by equally mixing based on dried weights, i.e. the mixture of degraded pine wood and HVS wastepaper, degraded pine wood with HVS and newsprint wastepaper, degraded pine wood with HVS and cardboard wastepaper, and the mixture of degraded pine wood with HVS, newsprint, and cardboard wastepaper. Boiled soybean water was used as an additional substance of the formulation. The termite survival rate and food transfer were evaluated using no-choice test. The food transfer was studied using test samples dyed with 0.1% Nile Blue A. The food formulations were also subjected to field test for six weeks to evaluate the termite attacks. The results showed that the highest food transfer efficiency was found for degraded pine wood and HVS wastepaper formulation, however, the survival rate was not significantly different among the formulations. The field test proved that the mixture formulation of degraded pine wood with HVS and cardboard wastepaper as well as that of degraded pine wood with HVS, newsprint, and cardboard wastepaper were attacked by termites to the failure level.Keywords: bait formulation, Coptotermes sp., food transfer efficiency, survival rate, termite control

Abstract

The effect of preservative treatment using carbon dioxide as a carrier solvent on wood physical properties and dimensional stability had been observed on three commercial wood species (Agathis sp., Palaquium sp., and Heritiera sp.). For the purpose of the study, wood samples measuring 1,5 (R) x 1,5 (T) x 15 (L) cm were prepared. Treatment was conducted at elevated temperature (50C - 350C) and increased pressure (60 - 80 kgf/cm2) on one occasion with five replicates using two specimens of each wood species for each treatment. The final treatment condition was maintained for three different periods (10, 20, 30 minutes). Results indicated that the physical properties and dimensional stability of the preserved wood were not significantly affected by the application of CO2 impregnation as carrier solvent. Key words: Preservative treatment, Carbon dioxide, Carrier solvent, Wood physical properties, Wood dimensional stability

Abstract

Damages of building construction due to termite attacks have caused high economic losses and therefore, efforts are continuously developed to overcome the serious problem. Baiting system is one way to control termite attacks as it consists of acceptable termite food sources, combined with a slow-acting substance lethal to termites. This study was conducted to produce termite bait materials from organic waste mixtures and evaluate its effectiveness against termite attacks in the field. The termite baits were produced by mixing paper, cardboard, and degraded pine wood, combined with leaves of Melaleuca leucadendron Linn assumed to be toxic to termites. Tapioca starch was used as glue and added to the organic materials mixture before pressed at room temperature with the target density of 1.0 g/cm3. The produced baits were placed in the field with signs of heavy attacks of termites, Coptotermes sp., and observed every three days for the termite elimination. Results showed that the bait formulation enables to significantly eliminate the termite attacks with high attractant properties. However, its effectiveness was still lower than the commercial bait due to its high capacity of water absorption, indicating the importance of further research on its mixture and glue formulation.
